EPL Support Matrix

This document defines the production support boundary for EPL.

Python

Compatibility target:

• Python 3.9
• Python 3.10
• Python 3.11
• Python 3.12

Current CI gate:

• Python 3.9
• Python 3.11
• Python 3.12

Cross-platform release smoke:

• Python 3.11 on Ubuntu
• Python 3.11 on Windows
• Python 3.11 on macOS

Release gate:

• Python 3.11 is the primary release validation environment

Operating Systems

CI-gated:

• Ubuntu latest
• Windows latest
• macOS release smoke

Optional Dependencies

Base install:

• pip install epl-lang
• supports interpreter, CLI, package manager, docs/lint/test workflows, and Python bridge

Native compilation:

• pip install "epl-lang[llvm]"
• requires llvmlite
• requires a system C compiler/linker such as clang or gcc

AI tooling:

• pip install "epl-lang[ai]"

Production Windows serving:

• pip install "epl-lang[server]"

Redis-backed features:

• pip install "epl-lang[redis]"

Runtime Targets

Production-ready and CI-backed:

• interpreter / CLI workflows
• package manager and manifest workflows
• maintained reference backend API and fullstack web app route smoke tests
• reference fullstack app CLI serve, deploy-generation, and generated Docker Compose deployment validation
• deployed backend/fullstack monitoring through the reference-app monitor workflow when URLs are configured
• Android reference project generation plus standard Gradle wrapper, lint, unit-test, debug, and release build validation
• desktop project generation and Gradle compile/test validation

Supported with extra toolchain requirements:

• native build via LLVM + system compiler
• standalone packaging workflows

Not yet release-gated:

• large-scale Android device/emulator validation
• long-running production web load benchmarks

Stability Contract

• epl/cli.py is the authoritative CLI implementation
• main.py is the source checkout wrapper over the same command surface
• epl.toml is the primary manifest format
• epl.json is legacy compatibility only
